Answer 1

▪Valor numérico
$\boxed{{( - \frac{1}{4} ab)}^{2} }$

° Para:

$\boxed{a = \frac{1}{3} }\\ \\ \boxed{ b = - 3}$

▪Procedimiento

° Sustituimos valores:

${( - \frac{1}{4} ab) }^{2} = \\ \\ {[(- \frac{1}{4} )( \frac{1}{3} )( - 3) ] }^{2} = \\ \\ ( - {\frac{1}{4} ) }^{2} {( \frac{1}{3} )}^{2} {( - 3)}^{2} = \\ \\ (\frac{1}{16} )( \frac{1}{9} )(9) = \\ \\ ( \frac{1}{16} )( \frac{1}{1} )(1) = \\ \\ \boxed{\boxed{\frac{1}{16} }}$
